Square Wave Generator Using Second Generation Current Controlled Conveyor (CCCII)

A novel prototype for the generation of square waveform using Second-Generation Current Controlled Conveyor (CCCII) is presented and implemented in this manuscript. The proposed topology has a single active device (CCCII) with only three external passive elements, a grounded capacitor and only two resistors. The functional block is devised and tested using Cadence Orcad tool. It gains the advantage of tunability of frequency by means of bias current (I
b
) and wide range of tuning is perceived. Supply voltage is fixed at ±2 V. Also the design is experimentally verified exploiting Current Feedback Operational Amplifier (AD844AN), Operational Transconductance Amplifier (LM13700) and few passive elements connected externally on a laboratory setup. Both the experimental and simulated results are depicted and matched with the analysis conceded. Elevated merits of the proposed circuit compared favorably with existing models from open literature. Statistical performance of the design is tested with Montecarlo analysis to establish robustness against resistance tolerance of 5%, the parameters such as Mean, variance and standard deviation are evaluated. Also the maximum power dissipation obtained is ~1.37mW (simulation-platform) and 9.4m W (experimental-platform).
